Beating heart mitral valve repair for a patient with previous coronary bypass: a case report and review of the literature.


ABSTRACT: Mitral valve reoperation, through a median sternotomy, for a patient with patent coronary bypass grafts is technically challenging and carries higher postoperative morbidity and mortality than a primary operation. We present a case of mitral valve repair using a beating heart technique under normothermic cardiopulmonary bypass that was performed 3 years after a coronary artery bypass operation. A limited (10 cm) right thoracotomy was made and cardiopulmonary bypass was conducted using the ascending aortic and femoral venous cannulation. The left atrium was opened while beating was maintained. Triangular resection of the prolapsed portion of the posterior leaflet and ring annuloplasty were performed. Completeness of the repair was verified by direct visualization under beating condition and transesophageal echocardiogram. This technique is a safe and feasible option for a mitral valve reoperation that excludes re-sternotomy, extensive pericardial dissection and aortic clamping, thereby minimizes risks of bleeding, graft injury and myocardial damage.
